Compositions of exogenous chemicals, particularly phloem-mobile exogenous chemicals, are provided for treatment of plants, wherein the composition comprises the exogenous chemical and an enhancing agent consisting of an anthraquinone or substituted anthraquinone. Specific compositions contain herbicides, particularly N-phosphonomethylglycine and herbicidal derivatives thereof, i.e., glyphosate. The compositions exhibit enhanced effectiveness compared to compositions in which the enhancing agent is not present. Also provided are processes for applying an exogenous chemical with an anthraquinone or substituted anthraquinone enhancing agent to achieve enhanced biological effectiveness. |
